exp_imageexp_imageExpImageExpImage (Operator)

Name

exp_imageexp_imageExpImageExpImage — Calculate the exponentiation of an image.

Signature

exp_image(Image : ExpImage : Base : )

Description

exp_imageexp_imageExpImageExpImageExpImage calculates the exponentiation to the base BaseBaseBaseBasebaseVal of an input image ImageImageImageImageimage and stores the result in the image ExpImageExpImageExpImageExpImageexpImage. If ImageImageImageImageimage contains gray values that would overflow the range of ExpImageExpImageExpImageExpImageexpImage, e.g., > 88.722839 for BaseBaseBaseBasebaseVal = 'e'"e""e""e""e", the corresponding gray values in ExpImageExpImageExpImageExpImageexpImage are set to the largest value representable in ExpImageExpImageExpImageExpImageexpImage (i.e., ).

Attention

exp_imageexp_imageExpImageExpImageExpImage can be executed on an OpenCL device for byte, int1, int2, uint2, int4, and real images. Note that the results of the OpenCL code may vary from the results produced by the CPU.

Execution Information

Multithreading type: reentrant (runs in parallel with non-exclusive operators).
Multithreading scope: global (may be called from any thread).
Automatically parallelized on tuple level.
Automatically parallelized on channel level.
Automatically parallelized on domain level.

Parameters

ImageImageImageImageimage (input_object) (multichannel-)image(-array) → object (byte* / int1* / uint2* / int2* / int4* / int8 / real*) *allowed for compute devices

Input image.

ExpImageExpImageExpImageExpImageexpImage (output_object) (multichannel-)image(-array) → object (real)
